CARPET-BEATER.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed July 24,1906- Serial No. 327,491.

To @ZZ whom t may concern.

Beit known that I, OseAn OHALLORAN, a citizen of the United States, anda resident of the city of New York, boroughof Brooklyn, in the county ofKings and State of New York, have invented a new and ImprovedCarpet-Beaten of which the following is a full, clear, and exactdescription.

The purpose of the invention is to provide a portable carpet beater,especially adapted to be operated by hand and which is of very simple,durable and economic construction.

A further purpose of the invention is to so construct the device that inoperation beater arms of opposing series will be automatically andintermittently raised and permitted to drop under spring control, thuswhipping a carpet in the same manner as practiced by hand.

Another purpose of the invention is to provide a means for holding allthe beaters out of the way within the body of the device when saiddevice is to be transported or stored away.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical central section taken practically on the line 1-1of Fig. 2,' Fig. 2 is a front elevation of the improved beater; Fig. 3is a side elevation thereof; and Fig. 4 is a front elevation of aportion of the cam shaft, a cam thereon and a section through a lift armin connection with which the cam operates.

The body of the device consists of side pieces 10, a connecting toppiece 11 and a ower connecting bar 12, preferably located aboutcentrally between the longitudinal edges of the side pieces, and thesaid frame may be of any desired length or dimensions.

A shaft 13 is fixed in the side pieces 10, being located at the bottomportion of the body, and said shaft is adapted to carry beaters arrangedin two series, a series A and a series A, the beaters of the two serieseX- tending from the shaft in opposite directions. Each beater is of thesame construction, and consists of a body arm 14 having a straight flatbottom longitudinal edge, and preferably the body arm 14 is thinnest atits outer end, and a shank member 15 which extends up from the inner endof the body arm 14 and connects with a ring member 16. The ring members16 are loosely mounted on the shaft 13, and the beaters of the twoseries are alternately placed on the said shaft and their ring membersare held suitably spaced by washers 17 or their equivalents.

A second shaft 18 is secured in the side pieces l() of the body at apoint above the beater shaft 13, and springs 19 are secured to the shaft1S, one for each beater. These springs 19 are connected at their lowerends to straps 20, which straps are secured to the rear or innerperipheral surfaces of the ring members 1G of the beaters, as is shownin Fig. l, the straps connecting with the beaters A being at that sideof the ring members of the beaters which face in direction of thebeaters A, while the straps which connect with the ring members of thebeaters A face in direction of the beaters A. A third shaft 21 is alsomounted to turn in the said body above the shaft 1S, and the shafts 13,18 and 21 are in vertical alinement. The shaft 21 is provided at one ofits ends with a crank handle 21., whereby the said shaft is turned. Aseries of cams B is secured upon the shaft 21. These cams correspond. innumber to the number of beaters employed, and each cam consists of an.elliptical body 22 and a segmental tongue 23 integral with the body.These cams B are spirally arranged on the shaft 21, so that the point ofone cam is slightly in advance of the point of the next. Two othershafts 24 and 25 are employed, and these shafts are xed shafts andextend from one side of the body to the other adjacent to thelongitudinal edges of the side piecesof the body and said shafts 24 and25 are located one at each side of and above the cam shaft 21.

A series of lift arms O and C are loosely mounted at their outer ends onthe shafts 24 and 25, the lifting arms O being mounted on the shaft 241and the lift arms O on the shaft 25; and the arms on one shaft extendbetween the arms from the opposing shaft, so that the arrangement of thesaid lift arms is alternate. The arms C are adapted to operate inconjunction with the beaters A, and the arms C operate in. conjunctionwith the beaters A.

A strap 27 or its equivalent is attached to its upper edge is inclinedor beveled, so that the inner end of each of the lift arms O, and

IOO

IIO

the said straps at their lower ends are se- Y cured one to the outerlongitudinal edge of the shank 15 of each of the beaters A, and straps27 a or their equivalents are secured to the outer ends of the lift armsC and to the outerv longitudinal faces of the shank members of thebeaters A. In the construction of each of the lift arms a longitudinalopening 26 is made, one end wall of each opening being more or lessbeveled. The end wall of the opening in arm C adjacent to the pivotedend of the arm is beveled, while the end wall of the opening in the armC adj acent to its free end is beveled.

When the cam shaft 21 is revolved the hub portion of a cam will engagewith the under face of the pivotal portion of the arm above it, and willlift the said arm more or less, and the upward movement of the arm iscontinued by the engagement of the convexed edge of the tongue of thecam; and as the lift arm operated on is raised through the medium of itsattached strap, the beater with which the said strap is connected islikewise raised, and as the beater is rocked in rising its spring 19 isplaced under tension; as the arm reaches the opening 26 in the lift armupon which it has acted it enters the said opening as is shown in Fig.4, and the arm is then drawn downward by the spring 19, which alsoforces the body section of the beater violently in engagement with thecarpet upon which the machine is placed.

In the operation of this machine, as the shaft 21 is turned the beatersare alternately raised and lowered at opposite sides of the machine anda constant whipping action on the carpet is obtained, which actionserves to free the carpet from dust without injury to its texture. Staystrips 2S are normally placed in engagement with the outer faces of theside pieces 10, being temporarily held thereto by set screws 29, whichenter suitable apertures 29L in said side pieces. When the device is setup, however, the stay pieces are removed from their vertical positionshown in Fig. 3, and are placed transversely of the bottom portions ofthe side pieces of the body at their bottom edges, and the set screws 29are then made to enter openings 30 at the lower portion of the sidepieces 10. The strips 28 extend beyond opposite longitudinal edges ofthe body so as to steady the body while the machine is in action. Thesestrips and likewise the lower edge of the body may be provided withcasters if so desired.

When the device is not in use the beaters are folded up within the bodyas shown in Fig. 3, and bars or pins 31 are passed through openings 32in the side pieces 10 adjacent to their longitudinal edges, crossing theouter faces of the up-lifted beaters and holding said beaters in theirupper position, producing a very compact package for transportation andstorage.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent,-
